The 2945B Communications Service Monitor is

the lightest, most rugged service monitor avail-

able with a full performance spectrum analyzer

as standard. For field work the 2945B provides

an excellent combination of instruments for all

types of maintenance work. In the workshop, it

provides all of the performance you would

expect for exacting measurements.

Field Operation

At under 12 kg (25 lb), the 2945B lightens the load to remote sites.The shape of the 2945B is ideal for carrying. The side handleensures that the instrument is clear of the stairs when ascendingbuildings and the depth is suitable for the 2945B to be operatedcomfortably when it is placed on the floor.

A large color transflective (improved sunlight readable) display aidsoperation under harsh viewing conditions.

An optional bail arm is also available. This option allows a stowagecover to be fitted over the front panel for storage of adapters and fur-ther protection to the instrument’s front panel. A selection of casesare available including a hard transit case, standard soft carrying caseor an integrated soft carrying/optional case allowing full operationwithout removal from the protective case.

Internal Battery

Utilizing NiMH technology the internal battery option provides 60minutes operation in the field.

Compact and light the 2945B is equally at home in the field as on abench.

Fast Warm Up - Fast Results

The standard TCXO allows results to be made reliably within aminute of switch on. Where even better stability is required, anoptional OCXO is available.

Stored settings may be recalled from internal memory or from amemory card, allowing fast and straightforward setting up.

Fast Full Performance Spectrum Analyzer - provided as stan-

dard

The spectrum analyzer provides spans from 100 Hz per division to


full span and also has a fully adjustable reference level. Speed is com-parable with analog analyzers, allowing real time adjustments over thedisplayed dynamic range. With the tracking generator provided asstandard, duplexers and filters can be aligned quickly and easily. Anoffset facility provides testing of equipment with frequency transla-tion. Channel stepping can be performed by defining an incrementand then using the FREQ keys. This is particularly useful whentesting multi-channel systems.

Live Look and Listen

This feature puts the 2945B above all its peers with the ability toexamine signals on the screen and demodulate them simultaneously.Intermittent interference can be isolated quickly and the signals theneasily identified. The trace can be saved to the memory card alongwith the time and date, providing factual evidence that can be recalledlater. This feature is particularly useful when looking for rogue trans-missions, especially on busy basestation sites.

From 2 µV to 150 Watts

The 2945B will measure the power of low level signals such as thoseencountered when monitoring off-air signals or those found whenprobing a circuit. 150 Watts measurement is provided without theneed for external attenuators, so high power base stations can bemeasured directly. Measurement accuracy of better than 10% isguaranteed all the way down to 5 mW on the N-Type connector, allow-ing radios to be qualified at low power levels.

Accurate RF Signals

The signal generator provides coverage from 400 kHz to 1.05 GHzwith +5 dBm output (+7 dBm overrange) and fast switching speed.Level accuracy is ±2 dB at all levels above -127 dBm.

Duplex - provided as standard

Full duplex operation is provided by the 2945B. This allows testing ofduplex radios as well as simultaneous testing of repeater transmit andreceive paths. There are no restrictions to the duplex offset.

PMR, Trunking and Cellular

The 2945 provides extensive support for the various tone signalingsystems used in Professional Mobile Communications such asDTMF, TONE REMOTE (Option), DCS and CTCSS. Also a highlyflexible user defined system enables the instrument to be configuredto accommodate a wide variety of other tone formats that are in use.

Additionally trunked networks are supported with network signalingprotocol simulations for MPT-1327/1343, LTR (available Oct 05) andEDACS radio / repeater measurements. Legacy analog cellular stan-dards are also available internally and include AMPS, TACS andNMT with all country variants provided.

Remote Control - RS-232 or GPIB

Remote control is provided with an RS-232 interface as standard. AnIEEE-488.2 interface (Option 5) can be fitted where other instru-ments are required to operate in a system with the 2945B.

Printing and Post Analysis

With the parallel printer port interface, screen dumps, automatic testresults or previously stored results may be sent to any parallel printer.These facilities are available as standard using the serial RS-232interface.

A screen capture facility is available so any screen displayed on the2945B Communications Service Monitor can be saved direct to a PC,via the serial port, as a bit map file.

A single trace dump command allows fast transfer of the spectrumanalyzer, OBW or transient analysis trace to be transferred as 249ordinate values for detailed post-proccessing and analysis.

Autorun - internal control

With the (optional) Analog Systems Card fitted, automatic testingwithout an external controller is possible. Custom tests may be writ-ten and run by the operator. Four programmable relay contacts areprovided with the optional parallel printer interface to allow remotecontrol of radios or test fixtures from built-in automatic tests.

Custom Programs

Users may program the instrument to suit their own specific needs.This is possible either by configuring any of the range of built-in pro-grams or by using the MI-BASIC interpreter to produce a customizedtest program that can be executed internally, without an external con-troller.

Memory Card - with real time clock

The Memory Card Drive meets the PCMCIA standard format for PCcards. The 2945B provides a DOS based filing system that allowstransfer of information to a PC fitted with a memory card slot.

Test setups, test results, screen dumps, spectrum analyzer coordinates and test sequences can all be stored on the memory card,allowing information to be easily stored and retrieved when required.



Reliability

The 2945B features high integration with a rugged chassis design tomaximize mechanical protection.

Audio Analysis

A comprehensive and expanded range of filter selection is provided asstandard, including band pass, lowpass and high pass. Optional fil-ters are available for psophometric weighting of audio signals anddemodulation of signals in a simulated radio channel bandwidth.

The standard 1 kHz notch filter provides for normaldistortion/SINAD measurements. Additional notch filters can beadded to enable distortion/SINAD measurements for signals in therange 50 Hz to 20 kHz where required.

The direct measurement of CTCSS is possible with the 300 Hz LPfilter, even with speech present.

Two comprehensive audio generators are provided as standard forinternal modulation or audio sources for transmitter stimulus.

External DC coupled FM is provided.

Comprehensive Oscilloscope

Analysis of audio signals, whether from the demodulated signal or theaudio input direct, can be viewed for further inspection. The oscillo-scope can either be combined with the measurement screen in theTx, Rx or AF test modes or ‘zoomed’ to a full screen display.Different levels of persistence can be selected to allow short or longterm effects to be captured.

Transient Analysis

The ability to capture transients on the rising or falling edge of awaveform provides a valuable tool for fault finding radios and radiosystems. The user has full control of the trigger level and input atten-uation as well as the timebase and five fixed trigger points, makingthis feature simple and flexible to operate.

Harmonic Analysis

An automatic harmonic analysis function is included in the 2945B.This complements the fast spectrum analyzer and allows a rapidcheck that the transmitter is not producing any large harmonics.

Tones Generation and Decoding

The tones menus include full remote control so that radio workshopscan further automate their tasks. It is possible to enter tones dura-tions of up to 20 seconds directly, simplifying operation with some ofthe more extreme tones systems in use. These and other improve-ments are in response to user feedback and allow better control of thetones from the top level screens.

POCSAG Decode - built in option

Off-air decoding of POCSAG signals is provided as an option. Thisallows tone, numeric and alphanumeric signals to be displayed.Signals with bit rates of up to 4800 bits/s can be automatically detect-ed making the 2945B an ideal surveillance tool. The 2945B can be setto detect all messages, a user selectable RIC (just like a Pager), or afixed message string.
